351c never came in a truck, but could be swapped in

351W looks like a small block

351M looks like a 351C and came in trucks

your so called ford guy isnt a ford guy if he said a 351M is a big block

post a pic of the motor

im pretty the 351m is big block, its 400 block
351M/400 = EIGHT valve cover bolt holes per side // 351W = SIX valve cover bolt holes per side.
351M/400: The fuel pump bolts to the left (drivers) side of the engine block / 351W: The fuel pump bolts to the timing cover.

351 is not a big block

Always broke
10-31-2009, 03:31 PM
Often confused because the tranny is the same pattern as the big block and they are the same block width as a 429/460

351 is not a big block

As i understand it the bick block small block thing comes from the tranny bolt patterns....not the block itself. There is a major difference in the block design from the c to the m and the w
I'm not sure if you would actually call any of them a big block but here is some info i found elsewhere......

ford doesnt use "small block/big block.
the 351C/351M/400 are 335 series engines.
they use the 'small block' ford Windsor series bore spacing of 4.36"
a 'bigblock' ford/chevy/dodge would have a bore spacing over 4.8" (the 385 series ford bigblock like the 460 use a 4.9" bore spacing)

351M isnt a "big block"
a bellhousing bolt pattern does not determine if a motor would be a "big block" or a "small block", if it did then the big block chevy would be a small block

W uses a fuel pump with 2 bolts spaced horizontally
335 series use a stud and a bolt spaced vertically
W thermostat housing is in the intake manifold at the front
335 thermo is in the front block extension

you can be as "sure" as you want, you just aint correct.
you can bolt the heads off that 351C/351m/400 onto the W motors, ford did it and called it a boss 302

351m Is a small block, Just had the big block bellhousing bolt pattern. I have a 351m and a 460. The blocks beside each other dont even compare. Yea it could be a 400, Thats just a 351m with different crank and pistons, Same rods.

m j knows what he's talkin about.Theres no such thing as a 351 big block.

Its kinda like how people like to call the 400 chev a small block 400... Why? All chevy 400's are small blocks.

So easy, surpised it hasnt come up before, the 351M is a 90* block, the connecting rods are 90* to each other, the 351 Windsor is a 60* block same as the 302, therefore interchangable. The 351M only looks like a big block cause its wider than a standard small block. And yes they did put in the same bolt pattern to tranny as the big block for interchangability issues in the trucks. The 351M is an awesome motor, I had one with 480 thousand k on it and still ran good when I sold it.

11-06-2009, 05:13 PM
wtf??
I am pretty sure all ford v8s are 90degree motors, the balance of a 60degree v8 would suck
v6 and v12 are 60 degree
351m is a large motor, no denying that, it has a 10.2" deck hieght which is really tall
and it has the big 335series heads which dont angle in on the exhaust side like a sbc or Windsor motor so they look massive too

Not really, all chev blocks are 60*. And most of the old pontiac and olds motors were a 90* block. Thats why when you see a pontiac 350 it looks huge compared to a chev 350. Again, most people will refer to the pontiac and olds 350's as big blocks. But they are not

more people should do reaserch on the net first to find the answer, insted of asking here as soon as something pops in your head. the peanut gallery just destroys dumb questions and comments.

Ya i don't think there are too many v8s that arent 90s. Just different deck heights and such as i understand. Researched it a bit ago when Fota tried telling me that 302s weren't 90[f]

Actually the real Ford freaks do use "big block " "small block".
Big Block V8 - 385 Series (6.1/370, 7.0/429, 7.5/460)
FE & FT Big Block V8 (332, 352, 360, 390, 406, 410, 427, 428)

There is also the very little understood sho v8 that was a short run motor, but is a 60 deg. v8. It's kinda weird. As a result of the 60 deg, it's not balanced and has a countershaft in it to maintain ballance.

As far as weather or not the M's are big or small blocks, ever hear of a cleavor motor? Was popular, sortof, in the late 80's. Basicly, its a small block with 2v M heads. Just based on the bore centers, it's n ot possible for a m to be a big block.

I do like how noone talks much about the fe motors though

Finally Extinct

I doubt anyone would intentionally use M heads on a clevor, the 351C 2V or the imported Aussie 302C heads are the choice for a clevor

So I read this whole thread and i dont see the answer to the question?
How do you ID a Cleveland?
I have a friend who says hes got a Cleveland in his 79 Ford.
We know 79's didnt come with a Cleveland but it could have been swapped in.
But how to ID , anyone know?

Spedley
11-20-2009, 05:07 PM
I "believe" that just the Cleveland heads have a 2 or a 4 on the flat exposed corner just outside the valve cover. In that pic, the corner is just flat with neither number on it.I have a set of heads with a 4 cast into that corner in the garage... 4bbl Cleveland heads. Fuckin huge ports... Not good for a 4x4... Well, maybe something that revs really high.

Gotta find a reference dealing with the block.

Ok spent 5mins on the net and found this

351 Cleveland
5-bolt straight valve covers 8 bolt 2-plane valve covers
radiator hose to the intake manifold radiator hose does not connect to intake
regular 5/8" spark plugs small 14mm spark

and this Casting ID numbers


351-C Block Numbers
2V - D0AE-A, C, E, G, J, L & D2AE-DA
4V - D0AE-B, D, F, H
Boss 351 - D1ZE-A, B
HO - D2AE-EA
CJ - D2AE-CA

I have a 4 bolt main D2AE block from a 1972 Mercury Cougar that was not a CJ or HO
the casting numbers you have are kind of BS.
the CJ and HO casting numbered blocks were used in all kinds of cars, the DOAE

to ID a 351M block vs a 351C block you are looking at deck hieght differences, motor mounts are different, bellhousing pattern is different
the Ms had a different thermactor passage setup in the intake and heads.

lots that i see in longhorns pic tells me its an M except the intake.
if I was standing looking at it I could ID it in seconds
is the intake a 4barrel or 2 barrel?

looks like a 351c deck hieght to me
on an M there is a 3/4" or so vertical bit of block at the front of the intake, and the head deck is raised higher.

the motor mounts on the block for a 351c are 2 bolts inline vertical like a 302W or 351W,
a 351M has 3 bolts and go into the block perpendicularly, so 45° from the ground
